In this descrip- Fig. '7 is a perspective detail of thehardware 55 tion only the parts on the right hand side of the door willbe described. It is to be understood, however, that these parts areduplicated on the left hand side of the door, where they operate inexactly the same manner.

Attached to the door section I9 on each side, at a point slightly belowits uppermost edge, are angle brackets 32 shown in detail in Fig. '1.The long leg of each angle bracket lies adjacent the inner face of thedoor and the short leg 33 lies adjacent the edge of the door section.

Pivoted to the short leg 33 upon the rivet 34 is the swinging bracket35. The bracket 35, as shown in Fig. 7, is composed of a metal stripformed into a long arm 36, and then bent to form the arm 31perpendicular thereto. The arm 31 is again bent at its outer end to formthe ilange 38 which is perpendicular to the arm 31 of the bracket 35,and parallel to the long arm 36 thereof.

While one end of the long arm 36 of the bracket 35 is pivoted to theangle bracket 32 at the pivot 34, the other end is provided with a rivet39 which forms a pivot for the free link 40 and also serves as an axlefor the wheel or roller 42. Afxed to the link 40 is the rivet 4I whichserves asan axle for the wheel or roller 43, as shown in Fig. 5.

Pivotally attached to the ange 38 of the bracket 35 is the vertical rod44 shown in Figs. 1 to 6, inclusive. 'Ihis vertical rod 44 is guided bythe ring bolt 45 through which it passes. The ring bolt 45 is secured tothe uppermost section I of the door. The vertical rod 44 is broken andprovided with a pivot 46 by which the lower portion 41 of the verticalrod is pivotally secured to the upper portion 44. This pivot is soplaced as to be in alignment with the joint at which the door sectionsI0 and II meet, when the door is in position to be opened.

Below the rod 44, 41 is the toggle 43, 4S. The upper end of the link 48of the toggle is joined to the rod 41 by the pivot 53. The lower link 49of this toggle is pivoted at 56 to the door section II. stricted andguided by the arrn which is pivoted to the door at 52 and to the pivot53 which joins the rod 41 and the upper link 46 of the toggle. The lowerlink 49 of the toggle is pivotally secured to the operating bar 54 atthe pivot 55. The operating bar 54 is also secured at its other end tothe rotatable plate 56 and is slidable within the guide 51, which issecured to the door sectionl I I.

The rotatable plate 56 is operated by the handle 58 and can be locked inthe position-in which it is shown in Fig. 1 by the conventional lock 59.

The operating bar 54 projects beyond the pivot 55 suiiciently far sothat it may be projected through a slot in the remote rail of thevertical angle beam I9 and serve as a bolt to lock the door in closedposition as is shown in Fig. l.

The door may be provided with an auxiliary sliding bolt 6U, mounted uponthe rear face of the door, which can be slid through a slot in theremote rail of the vertical angle beam I9 to lock the door in closedposition when the uppermost section I0 of the door is swung into openposition. Similar provision may be made for locking the door in closedposition by providing a hole 6I in the face of the vertical angle beamI9 through which a bolt may be projected to engage the bearing memberassembly which is shown in detail in Fig. 8. Any other suitable meansmay be employed to bolt the door against upward movement when theuppermost section I0 is held in open position.

The door may also be provided with a suitable handle 62 by which thedoor may be raised and lowered.

The operation of the door is as follows: When the door is in closedposition as shown in Fig. 1 the bearing for the uppermost section l@ isin the position illustrated in Fig. 5. The long arm 36 of the bracket 35projects horizontally from the vertical door section and the wheels 42and 43 lie upon the flat rail of the curved portion 20 of the angle beamI9 upon which the bearings of the door ride. The front of the framemember 63 of the door section I9 is borne against the stop I1 below thelintel I5. The arm 36 of the bracket is held in the horizontal positionby the vertical rod 44 which is operated through the intervening linksby the operating bar 54.

When the parts are in the respective positions illustrated in Fig. 5 thedoor cannot be raised, because the upper edge of the door section I9bears against the sill' I5 and the pivots I8 and 46 do not coincide andbecause the remote end of the operating bar 54 projects through thevertical rail I9 and bolts the door in that position. When it is desiredto open the door, whether the uppermost section I0 is alone to be swungopen to provide ventilation or the entire door is The range of movementof the toggle is re- Y.

to be lifted into its horizontal position beneath the ceiling of theroom, the lever 58 on the rota-table plate 56 is swung toward the right.Because of their eccentric pivotal mounting upon the plate 56 thehorizontal bars 54 are moved toward the middle of the door and theirends withdrawn from the slots in the vertical rail I9.

Simultaneously, the horizontal bars 54 swing the lower links 49 of thetoggles about their pivots 50 and the toggles are opened as shown inFig, 2. The toggle is guided into an almost vertical positon by means ofthe pivoted bar 5|, which swings about its pivot 52, and restrains thetoggle so that the links of the toggle assume practically a verticalposition. The horizontal motion of the -bar 54 is thus translated intovertical motion of the rod 44, 41, which is pivoted to the ange 38, atthe end of the long arm 36 of the bracket 35.

As the rod 44 moves upward it closes the angle between the long armV 36of the bracket 35 and the edge of the frame portion 63 of the uppermostsection I0 of the door. As the bracket 35 is restrained by theengagement of the wheels 42 and 43 with theat rail of the curved portion20 of the angle beam I9, the closing of the angle between the bracketarm 36 and the frame portion 63 can be effected only by the swinginginwardly of the uppermost section I0 of the door about the hinges I8, bywhich sections I0 and II are connected. The uppermost section I0 of thedoor thus swings rearwardly into the room which is yclosed by the door,and the upper part of the door frame 63 comes to rest on the arm 31 ofthe bracket 35, which limits the extent of movement of the frame '63 andserves as a carrier for the uppermost section IU of the door. At thecompletion of this movement the parts shown in Fig. 5 assume therelationship shown in Fig. 6. The relation of the parts in this positionis also shown in elevation in Fig. 2 and in sectional elevation in Fig-4.

It is to be noted that when the vertical rod 44 is projected vertically,the pivot 46 by which the rod is joined to its lower portion 41 isaligned with the hinges I8 at the junction of the door sections |||Y andIl, thus permitting the rod 44-to break at the hinge and-v swingrearwardly with the upperI door section l0. -This is best illustrated int-he sectional detailin Fig. 4'.

f With the parts in the positions shown in Figs. 2, 4 and 6, the doormay either be locked by throwing the bolt 60 through a slot in thevertical rail I9 or by projecting a bolt through the hole 6| in the faceof the rail I9, into the path of the bearing assembly mounted on sectionI2 of the door.

If it is desired to open the entire door after the uppermost section hasbeen swung into the position shown'in Figs. 2, 4 and 6, the bolts justdescribed can be released andV the doorA can be manually lifted bythehandle 62 with the aid of the springs or counterweights which may beconnected to the cables 23.

As the door is lifted the Var-ious bearings will ride upon the anglerail I9 about thev curved portion 20 and iinally upon the horizontalportion 2| of the rail aixed to the ceiling. The upper frame-piece 6 3of the uppermost section I0 of the door is borne upon the arm 3l of lthebracket 35 and the entire door section Ill is thus carried upon thewheels 42, 43 mounted upon the bracket 35, both about the curved track20 and throughout the horizontal travel of the `door upon the tracks 2|.The entire door can thus be rolled around the curve 20 and into ahorizontal position. No clearance of any kind is required above the doorand the rail 2| may be mounted beneath the ceiling of the room andspaced from it by merely the thickness of the door.
